UPDATE 10/01/2015
Would you experience VXLAN tunnels disappiaring issue like it happens
on RDO Kilo add following lines to ml2_conf.ini on each Compute Node :-
[agent]
l2_population = True
followed by `openstack-service restart`
I also have to notice that Nested KVM does provide significant performance
improvement on Haswell i5,i7 CPUs
*************************************************************************************
Per http://specs.openstack.org/openstack/neutron-specs/specs/juno/neutron-ovs-dvr.html
1. Neutron DVR implements the fip-namespace on every Compute Node where the VMs are running. Thus VMs with FloatingIPs can forward the traffic to the External Network without routing it via Network Node. (North-South Routing).
2. Neutron DVR implements the L3 Routers across the Compute Nodes, so that tenants intra VM communication will occur with Network Node not involved. (East-West Routing).
3. Neutron Distributed Virtual Router provides the legacy SNAT behavior for the default SNAT for all private VMs. SNAT service is not distributed, it is centralized and the service node will host the service.
Setup configuration
- Controller node: Nova, Keystone, Cinder, Glance,
Neutron (using Open vSwitch plugin && VXLAN )
- (2x) Compute node: Nova (nova-compute),
Neutron (openvswitch-agent,l3-agent,metadata-agent )
Three CentOS 7.1 VMs (4 GB RAM, 4 VCPU, 2 VNICs ) has been built for testing
at Fedora 22 KVM Hypervisor. Two libvirt sub-nets were used first "openstackvms" for emulating External && Mgmt Networks 192.169.142.0/24 gateway virbr1 (192.169.142.1) and "vteps" 10.0.0.0/24 to support two VXLAN tunnels between Controller and Compute Nodes.

Second libvirt sub-net maybe defined and started same way.

UPDATE 10/01/2015
Would you experience VXLAN tunnels disappiaring issue like it happens
on RDO Kilo add following lines to ml2_conf.ini on each Compute Node :-
[agent]
l2_population = True
followed by `openstack-service restart`
I also have to notice that Nested KVM does provide significant performance
improvement on Haswell i5,i7 CPUs
*************************************************************************************
Per http://specs.openstack.org/openstack/neutron-specs/specs/juno/neutron-ovs-dvr.html
1. Neutron DVR implements the fip-namespace on every Compute Node where the VMs are running. Thus VMs with FloatingIPs can forward the traffic to the External Network without routing it via Network Node. (North-South Routing).
2. Neutron DVR implements the L3 Routers across the Compute Nodes, so that tenants intra VM communication will occur with Network Node not involved. (East-West Routing).
3. Neutron Distributed Virtual Router provides the legacy SNAT behavior for the default SNAT for all private VMs. SNAT service is not distributed, it is centralized and the service node will host the service.
Setup configuration
- Controller node: Nova, Keystone, Cinder, Glance,
Neutron (using Open vSwitch plugin && VXLAN )
- (2x) Compute node: Nova (nova-compute),
Neutron (openvswitch-agent,l3-agent,metadata-agent )
Three CentOS 7.1 VMs (4 GB RAM, 4 VCPU, 2 VNICs ) has been built for testing
at Fedora 22 KVM Hypervisor. Two libvirt sub-nets were used first "openstackvms" for emulating External && Mgmt Networks 192.169.142.0/24 gateway virbr1 (192.169.142.1) and "vteps" 10.0.0.0/24 to support two VXLAN tunnels between Controller and Compute Nodes.
